Design a PI controller to drive the step-response error to zero for the unity feedback system shown in Figure P9.1, where

K G(s) = (s + 1)(s +3)(s+ 10)

The system operates with a damping factor of 0.4. Design for each of the following two cases: (1) compensator zero at -0.1, and (2) compensator zero at -0.7. Compare the specifications of the uncompensated and each one of the compensated systems. Simulate each one of the systems using any software program.

K G(s) = (s + 1)(s +3)(s+ 10)
